**@voxpelli/typed-utils** is a small JavaScript/TypeScript library that provides runtime helper functions and type‑guard utilities—such as type‑safe array filtering, object key checks, assertions, and an immutable `FrozenSet`—all designed to preserve and narrow TypeScript types without sacrificing plain‑JS usability. It’s aimed at developers who want a lightweight, type‑enabled toolbox for safer data handling and runtime validation in Node.js projects.
